The [18F]2-fluoro-1,3-thiazolyl moiety—an easily-accessible structural motif for prospective molecular imaging radiotracers
摘要:
2-Fluoro-1,3-thiazoles were rapidly and efficiently labeled with no-carrier-added fluorine-18 (t(1/2) = 109.7 min) by treatment of readily prepared 2-halo precursors with cyclotron-produced [F-18]fluoride ion. The [F-18]2-fluoro-1,3-thiazolyl moiety constitutes a new and easily-labeled structural motif for prospective molecular imaging radiotracers. Published by Elsevier Ltd.

F-labeled thiazole derivatives useful for imaging of metabotropic glutamate subtype 5 receptors (mGluR5) in living mammalian brain are disclosed herein. Also disclosed herein is a synthetic method for making the claimed thiazole derivatives under thermal heating or microwave conditions for aryl thioethers that provides the compounds in high yield. Imaging methods in which the claimed
